Listening messages on public channel

[MikroPoli]

I'm making a HUD for my boat and I'm having a small problem. I'm not an experienced script writer so it is probably just me. I'm trying to read feedback from the boat after executing some commands. I can see the text in the local chat window. For example [16:32] Bandit 55: Powering Engine... However when I listen to messages on channel 0 I don't get this message. I have no filters set in the listen call listenHandle = llListen(0, "", "", ""); 

Messages from other senders are coming through but not from "Bandit 55". Any ideas why this is happening? Thanks.

Simply opening a channel isn't enough.  Your script has to have a listen event in which it receives messages on the open channel and does something with them.  In your case, something very simple should do the job

listen (integer channel, string name, key id, string message)
{
    llSay(0, message);
}

Study the LSL Wiki ..... http://wiki.secondlife.com/wiki/LlListen#Examples

That's rather silly, of course, since you are already hearing the message in chat.  Therefore, I assume that you want do do something else with it. That something else goes in the listen event.

The boat is most likely using llOwnerSay or llRegionSayTo to send messages directly to you. These messages can only be heard by you and nobody/nothing else.

Rolig Loon Thanks. I do have the listen event in my script. What I meant is that I'm not capturing the reply from the boat in the listen event on channel 0.

Wulfie Reanimator If the message is sent by llOwnerSay or llRegionSayTo can I capture those in my script?

No

[MikroPoli]

Bummer  Any workarounds?

[Rolig Loon]

Not really, unless you have permission to modify the boat's script or, possibly, the boat itself.  With mod perms, you could edit or replace the script to do whatever you want.

[MikroPoli]

No mod perms. This is a popular boat (Bandit 55) so I'm sure the creator would not allow that. I'll just have to find a reliable way to maintain the state of the boat based on the actions of my own script.

This was my first post on the forum so I must say I was very pleasantly surprised how quickly I was able to get good answers to my problem. Thanks for your help guys.

I am not a sailor myself, so I do not know how the Bandit is scripted or what options the designer may have built into it.  You might ask, though.  Some scripters (like me, on occasion) will add a special channel that broadcasts selected messages ( or sends them by llMessageLinked ) so that you can pick them up with a custom script.

I think the different boats from the creator in question, are scripted by different programmers and hence behaving a little different, but all based on the BOSS Dynamic Sailing Engine.

On my (TMS) Ushuaia the documentation on the boat specifies, it is listening to channel /29000 and I can make my own HUD for example to send the basic commands like jib etc.

Try and look in the documentation to your Bandit.

Hi,  a friend of mine already spoke to the creator of the Bandit, and they will not work with anyone on this.  Her idea was to feed keyboard data to the boat via script to automate sailing tours - and she had asked me for help.  Perhaps some day, he will relent.  Btw, llRegionSayTo() works fine for communicating between objects, but llOwnerSay() only sends text messages to the owner of the object, not the object itself.  Best of luck!

I found the channel 29000 to be working on Bandit as well and I have all the commands in my HUD. Now I'm trying to get real time information displayed in HUD. It is the same information as the navigation instruments of the boat show. It would be more convenient to have in the HUD. I have speed, heading and depth already but getting any feedback from the boat does not seem possible.

Is the idea to have the boat sail automatically a pre set course? That sounds interesting

Yes, that was the idea, but there's no way to communicate the captured keystrokes back to the boat scripts.  There's no open API.  LOL.
